Yes, well done. But it doesn't handle all cases. It will only work if you limit yourself to a basic latin character set.

Problem with datagridview

(via Instant C#):
Dim chararrinput As Char()=strinput.ToCharArray()
Dim arrbyteinput As Byte() = New Byte(chararrinput.Length-2){}

Note that you have to specify the upper bound of the array in VB, not the length as in C#. (by the way, the online converters, including devfusion, do not catch this).

Hello every 1

I am trying to make certain row of a datagridview invisible through my program but i am receiving following

InvalidOperatoinException:

"Row associated with the currency manager's position cannot be made invisible."

I have noticed that this problem occurs only if a row is selected in the datagridview
(My Solution: I have set the row selection property to single row and i deselect the row before making it invisible) even then the error is still coming

<code> private void button1_Click(object sender, EventArgs e)
        {
            
            this.dgvActiveHorse.SelectedRows[0].Selected = false;
            
            foreach (DataGridViewRow dRow in this.dgvActiveHorse.Rows)
            {
                if (isClear(1, dRow.Index))
                {              
                    //dRow.Selected = false; (I have done this as well)
                    dRow.Visible = false;
                    Application.DoEvents();
                }
            }</code>

Hi,

I am trying to write text data to an xml file via an
XMLTextWriter object. When I try to initialize the
XmlTextReader object, I get an IOException: The process
cannot access the file "path/filename here" because it is
being used by another process. Any idea what could be
causing this?

with regards
prasad Smile | :)

It would seem that another process (or even the current process) is already accessing the file. Although the error message told you that... right?

I presume you mean the file.

You release the file by closing any file handles open to it. Ensure that no other applications are using the file. Ensure that when you open the file yourself you close it properly.

Then why didn't the error message say that? The error message did mention that another process was using the file already.

When you post a problem like this, you need to be a little bit more specific. What error message/code are you getting? Without this vital piece of information, you're on your own.

format problem

Hi,

i have one number and i want to transform in one string but with one fixed format:

EX:

if i have

int x=10;
int y=999;

my string must be

string sForX="0010";
string sForY="0999";

(i want to do that without to format the string manual (with for, while or.....) )

You can use String.Format:

int x=10;
int y=999;

string sForX=String.Format("{0:0000}", x); 
string sForY=String.Format("{0:0000}", y);

Hi all, just want to find out what the best method would be.

I have a dataset with a datatable and values, now I want to write that to a xml file. Is it better to use xmlDocument for that or xmlwriter?

Thanks in advance

He who laughs last is a bit on the slow side

darkcalin28-Mar-07 23:36

DataSet dset = new DataSet();
dset.WriteXml(path,null);

//this is the better idea
